Side rail use and bed-related fall outcomes among nursing home residents

OBJECTIVES: To analyze the effect of physical restraint reduction on nighttime side rail use and to examine the relationship between bilateral side rail use and bed-related falls/injuries among nursing home residents. DESIGN: Secondary analysis of data collected in a longitudinal, prospective clinical trial designed to reduce restraint use. SETTING: Three nonprofit nursing homes. PARTICIPANTS: To examine the first question regarding the effect of physical restraint reduction on side rail usage, we included all nursing home residents who survived a 1-year data collection period (n = 463). To answer the second research question concerning the relationship between side rail status and bed-related falls, subjects' side rail status for each of the four data collection periods was compared. The sample for this analysis includes only those with consistent side rail status (n = 319) for the four observations periods: either 0/1 side rail (n = 188) or 2 (bilateral) side rails (n = 13 1). MEASUREMENTS: Side rail and restraint status was directly observed by two research assistants, twice each night shift (10 p.m.-6 a.m.) for three nights at each of four data collection points. Nighttime fall-related outcome data were obtained from a review of nursing home incident reports during the entire 1-year data collection period (T1 through T4). Cognitive status was measured using the Folstein Mini-Mental State Examination. Functional and behavioral status was obtained using subscales of the Psychogeriatric Dependency Raring Scale. RESULTS: Over a 1-year period, there vas an increase in the proportion of bilateral side rail use for all three nursing homes. Based on the multiple logistic regression analysis, there was no indication of a decreased Rick of falls or recurrent falls with bilateral Side rail use, controlling for cognition and functional and behavioral status (adjusted odds ratio (AOR) = 1.13, 95% confidence interval (CI) = 0.45,2.03). Similarly, bilateral side rail use did not reduce the risk, of recurrent falls, controlling for cognition and functional status (AOR = 1.25, 95% CI = 0.33,4.67). CONCLUSION: Despite high usage of bilateral Side rails, they do not appear to Significantly reduce the likelihood of falls, recurrent falls, or serious injuries. Bed-related falls remain clinically challenging. The data from this study, coupled with increasing reports of side rail-related injuries and deaths, compel us to seek and empirically test alternative interventions to prevent bed-related falls.
